Hood, Tracy – Physics Teacher, 2012
Ask a typical high school student to draw a picture of how a bar magnet works and most of the drawings produced will show a "+" and "-" sign at the two ends. Some students will write "N" and "S." If you then ask some follow-up questions, they will often resort to talking about "charges" being responsible for the magnetism. For several years, I…

Milanick, Mark – Physics Teacher, 2012
Two of the most frustrating things for me as a teacher are the way units and jargon can get in the way of understanding concepts. When I teach pre-nursing and medical students about blood pressure, they end up memorizing a lot of information that would be obvious if they had remembered some of their basic physics--particularly the ability to…

Physics Teacher, 2012
Last month we saw that females make up about 47% of all high school physics students in the United States. This number has changed little since 1997. This month, we take a closer look at female representation by type of class. We last collected class-specific data in 1993; that year, 43% of all high school physics students were female. However,…

Gagnon, Michel – Physics Teacher, 2012
Early in the last century, Robert Millikan developed a precise method of determining the electric charge carried by oil droplets. Using a microscope and a small incandescent lamp, he observed the fall of charged droplets under the influence of an electric field inside a small observation chamber. In so doing, Millikan demonstrated the existence of…

Widmark, Stephen – Physics Teacher, 2012
Many physical systems are described by time-dependent differential equations or systems of such equations. This makes it difficult for students in an introductory physics class to solve many real-world problems since these students typically have little or no experience with this kind of mathematics. In my high school physics classes, I address…

Jumper, William D. – Physics Teacher, 2012
Many high school and introductory college physics courses make use of mousetrap car projects and competitions as a way of providing an engaging hands-on learning experience incorporating Newton's laws, conversion of potential to kinetic energy, dissipative forces, and rotational mechanics. Presented here is a simple analytical and finite element…

Fanaro, Maria de los Angeles; Otero, Maria Rita; Arlego, Marcelo – Physics Teacher, 2012
This paper discusses the teaching of basic quantum mechanics in high school. Rather than following the usual formalism, our approach is based on Feynman's path integral method. Our presentation makes use of simulation software and avoids sophisticated mathematical formalism. (Contains 3 figures.)

Physics Teacher, 2012
There are two sides of the physics teacher turnover equation: teachers leaving and teachers entering. This month we will focus on teachers' future teaching plans. As seen in the figure, about 5% of the 27,000 teachers who taught physics in U.S. high schools in 2008-09 were in their first year of teaching physics (but not necessarily their first…

Wei, Yajun – Physics Teacher, 2012
The topic of waves is one that many high school physics students find difficult to understand. This is especially true when using some A-level textbooks used in the U.K., where the concept of waves is introduced prior to the concept of simple harmonic oscillations. One of the challenges my students encounter is understanding the difference between…

Sabella, Mel S.; Van Duzor, Andrea G.; Passehl, Jennie; Weisenburger, Kara – Physics Teacher, 2012
Because of the diverse character of colleges and universities throughout the United States, it is naive to believe that a one-size-fits-all model of teacher preparation aligns with specific resources and student population needs. Exploring innovative models that challenge traditional programs is now being encouraged by organizations such as the…

Greenslade, Thomas B., Jr. – Physics Teacher, 2012
I spent the 1972-73 academic year on sabbatical leave at the Kingston, Jamaica, campus of the University of the West Indies. One of my duties was to give Saturday morning enrichment lectures to the students, and the best one was on suspension bridges. The demonstration lecture then went on tour to high schools in Jamaica and the Cayman Islands.…

Glasser, Howard M. – Physics Teacher, 2012
More schools in the United States have begun teaching physics to ninth-graders, but there continues to be limited evidence that such a change benefits students. Many arguments in favor of Physics First and the inverted sequence of physics-chemistry-biology are based more on the intellectual logic of the sequence than on measured outcomes. Paul…

Doherty, Michael; Fish, Vincent L.; Needles, Madeleine – Physics Teacher, 2011
Scientists and teachers have worked together to produce teaching materials for the Very Small Radio Telescope (VSRT), an easy-to-use, low-cost apparatus that can be used in multiple laboratory experiments in high school and university physics and astronomy classes. In this article, we describe the motivation for the VSRT and several of the…

Rebello, Carina M.; Hanuscin, Deborah; Sinha, Somnath – Physics Teacher, 2011
Physics First--a movement to invert the traditional science course sequence to teach physics at the ninth-grade level--is gaining interest. However, there is limited literature exploring how to support teachers in successfully implementing Physics First. To address this, a professional development (PD) program supporting a cadre of teacher-leaders…

Beeken, Paul – Physics Teacher, 2011
While perusing various websites in search of a more challenging lab for my students, I came across a number of ideas where replacing the string in an Atwood's machine with a simple ball chain like the kind found in lamp pulls created an interesting system to investigate. The replacement of the string produced a nice nonuniform acceleration, but…
